Y COOL ING DEVICE FOR BADIATORS-FOR AUTOMOBILES Application filedDecember 14, 1928. Serial No. 325,980.

This invention relates toan accessory capable of use in numerousdifferent associations, but primarily intended to be employed inconnection with a motor ofthe'internal combustion type and specifically,the cooling system of such motor.

It is an object of the invention to provide a device of this characterwhich, in use, will serve to prevent a cracking of the radiator is coreand will achieve this result by assuring a more rapid and evendissipation of heat than has generally been achieved heretofore.

A further object of the invention is that of furnishing an accessory ofthis nature the parts of which will-be relatively few in number andindividually rugged in construction, these parts being capable of beingmanufactured and assembled, as well as applied to the cooling systemwith facility and by unskilled 2e labor, so that an economical articleof this type is furnished.

An additional object is that of furnishing an accessory for thispurposewhich will have a pleasing appearance and which when placed inassociation with a radiator core will not injure the latter. r

With these and further objects in mind reference is had to the attachedsheet of drawings illustrating one practical embodiment of 0 theinvention and in which Figure 1 is a partly sectional view taken througha radiator shell and core and showing the same disposed in theconventional manner adjacent the motor block and furthermoreillustrating the accessory in applied position; Fig. 2 is an enlargedsectional view of such accessory, and d Fig. 3 is a partly fragmentaryface View thereof. 7

motor block in advance of which, in the usual manner, a fan 6 is carriedas, for example, by means of a bracket 7, this fan being 4 driven by abelt 8. In turn disposed in derstood that the water carrying with itsome In these'views thenumeral 5 indicates the advance of the fan is aradiator core 9 having of the surplus heat in the motor moves into thehead and then down through the honeycomb of the core, where it is cooledand thereafter. circulates. back to thelmotor, either under theinfluence of a pump or incident to the a natural circulation induced. byheating and cooling of the fluid. In any event, in order to assure aflow of air through the interstices of the radiator, this airstreambeing sufiicient to effect cooling, the fan is provided.' Undercertain conditions it has been found that that portion of the radiatorcore which receives the water heated to the highest degree tends tocrack under the action of such heat. This defect is attributed to theextreme conditions to which the core is subjected at this point, to

wit first, the most highly heated water is within the core adjacent thepoint at which it is liable to crack and, secondly,'too greatan amountofair is sucked through the radiator core at this point, resulting inrapid fluctuations of temperature and corresponding expansions andcontractions of the metal from which the core is formed. j i

. In order to overcome difficulties in this con i nectiona coolingdevice is attached to the .radiator' in order to conduct surplus heatfrom this local section of the core. Thisconducting element preferablyincludes bracket portion 12 through openings in which bolts 13may'eXtend, these bolts mounting washers 14: of suitable material toassure against dam age to the radiator core and carrying nuts 15 toassure a proper clamping contact. The bracket, adjacent its upper end,mounts a disk 16 to which plates 17 are secured, these plates carryingor being encircled by a band portion 18 which, if desired, may have aradial series of projections 19 simulating in appearance the cylindersof a motor. A bracket .20 has its inner ends attached to the outer edgeof the band 18 and mounts one section of a ball bearing 21, the oppositesection of which may conveniently mount a spinner 22 having blades 23secured thereto. 5 These blades acting as a fan, under the influence ofthe air currents, will necessarily revolve andas a consequence of beingin line with the air column drawn inwardly by the fan, the speedof'revolution will be comparatively high. This is quite independent ofthe impulse imparted to the fan incident to the movement of the vehiclewith which it is associated. Irrespective of this, however, it 5 will beobvious that in so revolving the fan or miniature propeller willnecessarily break up any local and intense air streams induced by therotation of the fan 6.

Thus, by means of the present accessory a q structure is provided whichserves constantly to conduct heat away from that portion of the radiatorcore which is subjected to the highest degree of temperature. Moreover,such accessory serves to prevent too intense (in-face cooling at thislocality and by means of the present invention it is moreover feasihleto mount the accessory on the core without ury thereto, aside from thefact that a novel construction is furnished which will 29 operateoverlong periods of time without any attention.

As a consequence it has been discovered that the likelihood of damage tothe radiator is reduced materially and moreover, the ac ccssory thusprovided is pleasing in appearance and ornamental when applied to thevehicle with which it .i associated.

From the foregoin it will be appreciated that, among others, the objectsspecifically :,-;raforementioned are achieved. It is intended,

however, that numerous changes in construction and rearrangement of theparts might be resorted to without departing from: the spirit of theinvention as defined by the claim.

Having described my invention, what I claim as new and desire to secureby Letters Patent is A device of the character described includao ing aband, a bracket extending in advance of the same, a bearing carried bysaid bracket, a spinner mounted upon said bearing and overlapping saidband and propeller blades secured to said spinner.
